Revised Jetting Specs NEDW

Girard,

Thats with the RBD carb mod though, right? I have a few of those at home from my KTM days, as they were OEM or in the OEM kit supplied. How would you describe the required jetting after the RBD mods compared to before? I think that most conclude the new 38mm carb tends to run richer and needs leaner jetting than the old PWK AS.

Thats what I have found with the ASII. Definately needs leaner jetting. I rode my bike again yesterday with the 40 NEDJ#2 172 Main. I'm still super impressed. Its crisp off the bottom, smooth through the middle, and rips on top.

After many comparisons back and forwarth with the N3 range its much much smoother and mellower compared to n3. I agree with those who have said its soft.

Most of my riding is technical 1st and 2nd gear with poor traction. Wet red clay, wet roots, off cambers, rocks, mud and pine needles. For me the soft bottom end just keeps the bike moving forward. If traction gets better I find myself carrying more revs and staying in the meat of the power. If I need more instantly the clutch is only ever a finger away.

That's with the RB carb.
Like Jakobi said,it does have to be jetted leaner. Guys I ride with that have KTMs, said they jet their bikes (ASII) leaner than usual.
The NOZJ may be a better needle. I didn't have one laying around to try.

I settled on a NOZH needle for my bike.

What pilot, clip, and main did you settle on? Temps elevation etc?

I must say I liked the delivery of the stock needle (n1ef) which is the same tapers as the NOZ. Think the NOZ is a half clip leaner possibly. For me with the F diameter it was too rich even at top clip, would spooge, load up, smoke, and guzzle fuel like it was going out of fashion.

Down the track I might give a NOZI/NOZJ a burl for comparisons sake. I know Bailey speaks highly of them too!

been messing with my set up ...
gotta say i'm liking the nedw a lot more! Temp was 38F to 45F today wet muddy melting snowy conditions. 42 pilot 4th slot, 175 main. power delivery is electric motor smooth, bike chugs through anything. It was kind of rich on the 4 slot. Probably could have run it in the 3 slot. If I were to run it this winter I think I would bump up to a 45 and 178 or even 180. I'm guessing that for the summer MJC's 40 and 172 is probably spot on! Right now I'm digging this bike alot more than I was back in August and September. :D

Now I can start messing with my chassis set up .....

I'd been running the Jakobi-approved ;) NEDW-2 (a/s 2-3/4, p42, m175) myself in our recent 45-50F weather, and was loving the electric smooth bottom end on the '11 300 Six Days, but was a little less enthused about the transition to mid.

Friday was nudging 60F, and since it was a play day, I spent some time adjusting the airscrew and experimenting with pilots. Ended up with a p40, a/s 1 setting that absolutely rocks - still very manageable down low, but much quicker to transition to the mid and consequently easier to wheelie over logs. The top end makes me giggle ...

Still interested in trying the NEDJ and NOZH needles, but at this point that's simply a scientific pursuit.
 
Braap braap braap! I haven't gone for a ride in weeks. I'm withdrawing! Need to go and put this 40 NEDJ#2 172 through its paces!
 
I did not like the nedw, but the N3EJ is working well for me

50-200' 60-80 degrees 40 pilot with 180 main riding mostly in sand with a 36mm on a 250

it could be a little richer, I'm on #3 right now, it's very crisp and smooth, the cck #4 I had in was richer and it had slightly better roll on throttle

What did you not like?
 
these jet needles your talking about (NEDW) have you a part number, Ive been searching for two days with no joy, trying Suzuki parts, keihin parts but coming up with naf all.
I'm UK based and just wondered if there is any difference in part numbers etc

The NEDW needle is from a 2007 RM250 Part Number is 13383-37FL0, described as NEEDLE, JET (NEDW).

Anyone tried the NOZE KTM needle? Believe it turns the bike into a tractor

I believe the NOZx and N1Ex are very similar in profile. Bailey was running a NOZH in clip 1. N1EF stock needle is only a half cliip and 1 step different in diameter. I personally found the bike tractored well but would load up in the ST too quick. Smoked like a chimney!
 
My bike smoked like crazy with the N1EE needle. I liked the power but it was just too rich down low even with a 38 pilot. Happy to say that I swapped in my new NEDW needle and I'm very impressed with how much it cleaned up the smoke. Power is nice and linear but not anemic. The air screw adjustment seems to have more of an influence on how the bike runs now.
2011 250 38 carb
42 pilot
NEDW 3rd clip
178 main
200', ~45F
 
I tried the NEDW yesterday (comparing to the N3EJ that I was stoked with) and only kept it in for 30mins. To me it was too linear (almost 4 strokey) and lacked a bit up top. Put the N3EJ back in and it validated my thoughts, my jetting is spot on with this needle.

I had recently removed all of the free play from my PV actuator plate and really believe this has made a huge difference (Plenty off the bottom and is an arm puller at full noise!!!). Suggest to everyone that you inspect your actuator plate for any free play before digging too much into jetting.

Funny thing I am now back to stock jetting (from the shop), only adjustments are S3 head (high comp plate) and PV adjustment.
